NITED STATES PATENT FFICE.

MARTIN ARMSTRONG, OF VELASCO, TEXAS.

TWO-PIECE BOX.

SPECIFICATION forming part of Letters Patent No. 637,757, datedNovember'28, 1899.

Application filed April 29, 1899. Serial No. 715,011. (No model.)

To all whom it may concern:

Be it known that I, MARTIN ARMSTRONG, a citizen of the United States,residing at Velasco, in the county of Brazoria and State of Texas, haveinvented certain new and useful Improvements in Two-Piece Boxes, ofwhich the following is a specification,reference being had therein tothe accompanying drawings.

This invention relates to boxes or crates of cardboard, thin veneer, orother like material.

The object of the invention is to produce a box from the material, saidbox being composed of two rectangular blanks, whereby there isabsolutely no Waste in cutting the blanks from rectangular sheets. Theblanks can be shipped flat, so that freight charges are light. The boxwhen assembled has a raised interior bottom, which looks all the partsin position, as will be explained.

Figure 1 is a plan of the blank which constitutes the sides and ends ofthe box. Fig. 2 is a plan of the blank which forms the bottom and sidecovers. Fig. 3 is a perspective of blank of Fig. 1 folded to the form itassumes in the box. Fig. 4 is a perspective of blank of Fig. 2 in thefolded position. Fig. 5 is a perspective of the box complete, one cornerbeing broken away to show the relation of parts.

The blank A, Figs. 1 and 4, is rectangular and is scored or foldedtransversely on lines 1 2 3 4, so that the part'A' may form thefoundation of one of the box sides, the parts A A, the box ends, and theparts A A overlap to form the foundation of the other side of the box.

The blank B, Fig. 2, is also rectangular, and in width slightly lessthan the length of side A of the blank A. This blank is grooved, scored,or folded on lines 5 6 7 8, and if the material is at all thick thenthese scores are double, as indicated. With quite thin material onescore or fold of this double score might be omitted. The grooves orscores 9 and 10 define the outlines of the box-bottom 13 and the narrowfolds or flaps B B determine the elevation of the bottom above the loweredge of the box. B B indicate flaps which turn up over the box sides,and B B the flaps which enter inside the box sides, as indicated atFigs. 4 and 5.

The parts B B of blank. B between the double scores turns over or underthe top and bottom of the rectangular or square body A. If the materialof body A is quite thin, this part of blank B will be merely a singlefold, the elasticity of the material allowing it to close against thesides of the part A.

The downturned flaps B extend inside the box below the plane at whichthe bottom B is held by flaps 13". Thus when the box is assembled allthe parts are held with considerable firmness by the bracing effect ofthe bottom B and the wedging effect of ends of B entering between B andA or A A For fruit-boxes this device is specially well adapted, as theraised bottom permits packing without danger of bruising the fruit inslightly-rounded boxes, so that the fruit can shipped in fine condition.The triple thickness of the sides is not a great objection in the matterof expense, as the boxes can be pulled apart and returned as fiatblanks, so that the same box may be used several times.

The groove or score 11 on flap B is to assist in cupping said fold orflap, so as to slip it into the side of bottom, locking both side andbottom, substantially as described. The groove or score is not necessaryon very light material, but very necessary on heavy stiff material.

What I claim is 1. A two-piece box consisting of rectangular blanksfolded as described, one blank forming a rectangle or square open at topand bottom, the other forming an uplifted bottom and side flapsextending both outside and inside said rectangle or square, and allparts held in place by the bottom or side flap, substantially asdescribed.

2. The blank B for a box bottom and sides, said blank having thegrooves, scores or folds 5, 6, 7, 8, 9, 10, 11 to define the sides andraised bottom, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

MARTIN ARMSTRONG.
